I don't mind if I'm wrong. I just don't think pointing to the pressure distribution on the top surface of the hood tells the full story, or that the underhood pressure isn't a factor.

Under hood pressure should be counted for the venting. Pressure difference really makes air move.
I did an experiment for the vent at the cowl area on 2016. With the help of a Gurney flap, at least it blows out some air. I guess a blocking vertical barrier that divides low pressure zone and high pressure zone could help more.
I know it cannot blow out as much air that hood vent can. But could be better than nothing.
